This is not a unit on whales, but it offers supplementary documents that could accompany a research unit on whales - - an excellent topic to extend a unit on sound! Most of the documents cover sentence types, and proper sentence construction and punctuation. However, there are also some reading activities practicing such skills as drawing conclusions, reading maps, visualizing, and reading for detail. Unfortunately, I authored these documents a long time ago, and I do not have answer keys to them. Many, however, are easy to provide answer keys for. Though this is NOT a research unit on whales, all of the activities are related to the topic of whales, and students should learn a thing or two about whales by the time they have completed all of these activities.
PLEASE ASK QUESTIONS before purchasing. I do not want you to be dissatisfied.
